Learning Cryptography and Network Security

- Hello, I'm Lisa Bock, and welcome to Essentials of Cryptography and Network Security. Today, a large percentage of data is stored electronically. As a result, individuals and businesses need assurance that their data can be moved and stored securely. Encryption plays an essential role in protecting information. In this course you will gain a basic understanding of the various cryptographic and hashing techniques that are used to secure data, as I introduce the concepts and principles of cryptography.

I will review some of the historical aspects of encryption and the use of encryption, such as providing confidentiality, integrity, authentication, and accountability. I will present an overview of the main classes of encryption, such as symmetric and asymmetric encryption, along with commonly used algorithms. I will review hashing, message digests, and even passwords. I'll even demonstrate an SSL transaction and show you just why Web is insecure.

Now, let's get started with Essentials of Cryptography and Network Security.
